About Dioxycle
Dioxycle is pioneering breakthrough carbon utilization technologies that convert industrial emissions into sustainable chemicals with unprecedented energy and cost efficiency, starting with ethylene, the world's most used petrochemical. By displacing fossil fuels for the production of key chemicals, Dioxycle has the potential to ultimately reduce over 800 million tons of CO2 per year, representing ~2% of the world's emissions.
Our team is innovating across chemical, mechanical and system engineering to turn carbon transformation into an economically feasible, industrial reality by developing a completely novel technological approach. Having completed our medium-scale Proof-of-Concept, we are now working towards our first-of-its-kind industrial-scale electrolyzer and are assembling key partnerships for future commercial roll-out.
We are supported by world-class funders including Lowercarbon Capital, Breakthrough Energy Ventures and Gigascale Capital and have raised $26M to date. We operate from two centers in Paris and California (so whether you are passionate about outdoors or good food/art scenes, we have a location for you to join!)
Your Mission
Dioxycle is developing an in-house web platform to control lab-scale electrolyzers and industrial prototypes in its different facilities while collecting operation data.
